GEORGE WATSON, OF LONDON, AND NEVILLE BROUGHTON.LUDLOW, F WORCESTER,ENGLAND.

T 0 all whom it may concern:

Be it known that we, Gnonon WILLIAM lVA'rsoN, residing in London,England, and NEVILLE BROUGHTON LUDLOW, residin in \Vorcester, England,subjects of the mg of England, have invented certain new and useful Imrovements in Pressed-Steel Detachable eels, of which the following-is as ecification. v i 7 his invention is for improvements in or relating todetachable wheels for automobiles and like vehicles.

Accordin to the presentinvention a detachable w eel comprises incombinationtwo dished wheel-parts held together faceto-face with theirconcave surfaces opposed to one another, each of-which, wheel-partscomprises a dished disk formed with a circumferential flange whichextends outwardly from the plane of the wheel and away from thecompanion disk and is, at its outer'margin, turned radially away fromthe wheel-center to accommodate theedge of a tire together with a bandclosely en circling both of the said wheel-parts. and resting on thatportion of each 'circumferen tial 'fiange aforesaid whichextendsoutwardly from the plane of the wheel and away from the companion disk.

A feature of the invention. comprises a construction in which the saiddisks are in contact with one another near their outer :ircumferences,the band encircling both the wheel-parts to bridge across a gap whichoccurs between the circumferential flanges aforesaid where they turnoutwardly from one another and from their respective :lisks.

Another feature of the invention consists in the wheel-parts havingportions removed in the region of the valve and the two disks )eing soshaped that they are in contact around the margins of the holes when thehole .in one of themisin register with the hole in the other:-'- e c Theinventio' i'iifurther includes a method if forming a detachable wheel-intwo separate paitsi'which consists in taking a rim navingltheiform of aring which is, at each )f' its; two outer margins turned radially mayfrom the wheel-center to accommodate zhe edge of a tire and dividingsuch a rim .nto two circular parts by a circumferential :ut in itintermediate of its two upturned Specification of Letters Patent.Patented Aug. 16', 1921.

margins, and securing to each part so formed a dished disk. ITheforegoing and other features of the invention will be more clearlyunderstood from the following description of several preferred forms ofthe invention illustrated y way of example in the accompanying drawingsin whic Figure l is a partial-diametral section through one form'of rim;

Fig. 2 is a part section of the same rim through the center of thevalve-socket thereon;

Fig. 3 is a view of the inner surface of.

the rim looking upwardly in Fig. 2;

F ig. 4 isa section on the line IVIV of Fig. 3;

' Fig. 5 is a detail of a portion of the central band;

Fig. 6 is a partial diametral section of a modified construction. of rimsimilar to that illustrated in F igs.-15;

Fig. 7 isa diametral section of another modified construction of rim;

Fig. 8 is a partial section form of rim-shown in Fig. 1. Like referencenumerals indicate like parts in the several-figures of the drawings.

Referring. first 011 all to the construction illustrated 1n Figs. 1-5,the wheel'is formed in two similar halves, in each of which the body ofthe wheel and a trough section rim are together pressed out of a sheetsteel disk. Each half consists of a central dished disklike portion 1,an out-turned flange-portion 2 stepped at 3 and havin at its outermargin an upturned and slig tly inturned edge 4 shaped to engage theedge of a tire. wheel-part is so formed that the two parts will engageone another near'the outer peripheries of the disk-portions 1, as shownat 5 but are spaced away from one another in a gradually. increasingmanner toward the central or hub-portion. Eyes or central orithrough theEach fices are formed at 6 and the marginal porand struts- Sf)flC8daround the hub at equal intervals. 11 the example illustrated the disks1 are formed with holes for the reception of the connecting-devices andthe marginal portions of theseholes are inturned inwardly as at 7 toafi'ord bearing surfaces for the nuts and bolts respectively.

Each connecting-device is similar and comprises a bolt 8 and a nut 9having lindrical' portions to fit within. the inturne edges 7, the nutengaging on a screw-threaded end 10 of the bolt. The bolt-8 isflanged at11 to 1 engagethe outer surface of one of the disks and. the flange-11-i8 received within a recess on the inner face of one of the flanges12 of the detachable hub. Extending beyond the flange 11 is a screwthreaded projecting end l t-of thebolt 8 andzthe two flan es 12 and thewheel-parts 'are drawn toget or by means of an enlarged head 13 of thenut 9 and a nutengaging the screw-threaded form their respective disks.v

strutted "y means of tubular sleeves 16, each of whichtispformed with acentral portion of suchdimensions as to constitute a sliding fit on thebolt 8 and withflared end portions within-which the inturned edges 7will be accommodated. Thus, the sleeves 16 resist the compressivestresses imparted to -the two wheel-parts by the nuts'and bolts 8 Theother-set of connecting-devices for the wheelarts. is disposed near theouter peripheries of the disks 1 and each connectingdevice of this setconsists of a bolt 17 and a nut 18 whereof the shanks of the bolts areformed of square section and are, received in, either circular orsquare-section holes in the disks 1. I 1

An endless band 19 closely encircles both the wheel-parts and rests onthose out-turned portions of the latter between the shoulders '3 so asto bridge across the ga which would otherwise occur-between. the anges 2where they turn outwardly from one another and In order-to accommodatethe valve-stem ofan inner tube of the tire the band 19 is' orificed at119 and is rovided with an inwardly-extending sti ening boss 20surroundmgithe orifice 119, see Figs. 2-5. The

i surfaces of the disks are pressed out to fit closely around the boss20 as illustrated. Each of thej'disks 1, in the region of the boss 20,has a portion removed at 21 to'provide two holes which, when thewheel-parts are "assembled, register with one another. The

' edges of the removed parts 21 are cut flush I 60 with the inner end ofthe boss 20. The disks are so shaped that when the parts are. as-

sembled the disks will be in contact around" the mar 'ns of the holes 21to revent the access 0 water or grit or other oreign material into thespace between the disks.- This posed inner faces of the disks 1 areformation is clearly illustrated in Fig. 2, in which the referencenumeral 22 is employed to indicate where the disks are pressed togetheraround the margins of the holes 21 and the reference numeral 23 is usedto indicate the portions of the disks which are left to encircle theboss 20.

In Fig. 6 the rim is of the same general construction, with theexception that the stepped portions 3 are omitted, the flanges 2 beingsmoothly continuous wlth the disks 1, theband 19 being shaped to closethe gap. which would otherwise occur between the outer edge of thetire,may be taken and divided by a circumferential cut as at 25. To eachof the separate rings thus formed is secured a dished disk 1, similar ingeneral form to the dished disks 1 previously de' scribed. The disks arefl'anfged at their outer peripheries at 26 and the' anges 26 may bewelded to their respectiverim-parts.

By securing the heads of the bolt 17, as for example by spot-welding tothe disk 1, the bolts remain perfectly rigid after the front wheel-parthas been removed, thus facilitat-' ing ready replacement of thewheel-part when desired.

Moreover, awheel constructed as herein;

before described, can be use-d as a spare wheel as it is adapted for usewith known I constructions of standard flanged hub and can be detachedtherefrom and replaced thereon in precisely the same way as can a woodenor other well known kind of wheel.

A further advantage of the invention is that the manufacture of theWheels is considerably simplified and the cost of production reduced byforming each disk and its flanged part by pressin it from a metal disk.

What we claim as our invention and desire to secure by Letters Patentis 1.
